The World's Oldest Water Is Even More Ancient Than We Realised

A hidden reservoir deep underground.

Scientists have discovered the world’s oldest known water in an ancient pool in Canada that’s at least 2 billion years old.

Back in 2013 they found water dating back about 1.5 billion years at the Kidd Mine in Ontario, but searching deeper at the site revealed an even older source buried underground.

The initial discovery of the ancient liquid in 2013 came at a depth of around 2.4 kilometres (1.5 miles) in an underground tunnel in the mine. But the extreme depth of the mine – which at 3.1 kilometres (1.9 miles) is the deepest base metal mine in the world – gave researchers the opportunity to keep digging.

“[The 2013 find] really pushed back our understanding of how old flowing water could be and so it really drove us to explore further,” geochemist Barbara Sherwood Lollar from the University of Toronto told Rebecca Morelle at the BBC.

“And we took advantage of the fact that the mine is continuing to explore deeper and deeper into the earth.”

The new source was found at about 3 kilometres (1.9 miles) down, and according to Sherwood Lollar, there’s a lot more of it than you might expect.
